[Bug c/45410] New: constant not optimized / propagated

["reza at parvan dot net" <gcc-bugzilla at gcc dot gnu dot org>]

gcc -Wall -O3 -S test.c
doesn't seem to propagate constants correctly.

Notice that ss is declared static, therefor everything is known at compile
time.

Code:
#include <stdio.h>

struct s {int i;int j;};
struct s static ss={77,2};

int
main() 
{
        ss.j += 88;
        printf("%d\n",sizeof(ss));
        return ss.i+ss.j;
};
